• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"\\\"\\\\"((\\\\"((practice guidebook) OR (practical guidebook)) to (biostatistics OR (((biostatistics OR biostatistics) OR biostatistics) OR biostatistics)) AND epidemiology.\\\\\") OR (\\\\"((practice guide) OR (practical guide)) to statistics AND epidemiology.\\\\\"))\\\\"\\\"\\"\"".
• Removing quotes may allow a broader search: \ \\ ((\\ ((practice guidebook) OR (practical guidebook)) to (biostatistics OR (((biostatistics OR biostatistics) OR biostatistics) OR biostatistics)) AND epidemiology.\\\ ) OR (\\ ((practice guide) OR (practical guide)) to statistics AND epidemiology.\\\ ))\\ \.
